Abstract: In an electronic ultrasonic volume throughput meter for fluid media, a pulse generator (14) generating a frequency (f0) repeatedly triggers a measuring cycle which consists of a transmitting phase, a receiving phase and a calibration phase during which a change-over switch (18) exhibits different positions (a, b, c). When activated by a control element (9), a pulse generator (43) generates a measuring pulse which can be switched to at least one of the measurement transducers (6, 7) by the change-over switch (18) in its third switch position (c). A counter (42) starts due to the rising edge of the measuring pulse generated by the pulse transmitter (43), after the start counts the number of wave trains of a frequency (f2) sent by a scanning generator (11) and stops due to the rising edge of the measurement pulse received after it has passed through a measuring tube (2) from one of the measurement transducers (6, 7). The result of the count (NT) is proportional to the velocity of sound (vs). The pulse generator (14) is activated via a squaring element (51) by the result of the count (NT) of the counter (42), and this varies the frequency (f0) of the pulse generator (14). As a result, the velocity of sound (vs) is taken into consideration in the measurement of the volume throughput. <IMAGE>

Patent EP-0459627-A1 (EP)
Inventor: SMITH LAWRENCE A JR
IPC: C07C7/10
Filed: 1991-04-29
Abstract: A process for removing dimethyl ether (DME) and methanol impurities from C₄ hydrocarbon stream without substantial loss of C₄ hydrocarbons by fractionating a C₄ hydrocarbon stream containing DME and methanol at low levels, e.g., less than 5 wt.% to produce an overhead of about 20 to 40 volume % of the C₄ stream, condensing the overhead, contacting the condensed overhead with about 1 to 5 volumes of water, thereby removing a portion of the DME and methanol from the C₄ stream, returning substantially all of the C₄ stream, except the small amount solubilized in the water, to the fractionation and flashing the solubilized DME and hydrocarbons from the water. The fractionation and extraction are preferably carried out at elevated pressures, e.g., 200 to 300 psig to avoid refrigeration of the overhead condensation. The flashing of the DME and hydrocarbons is carried out by reducing the pressure on the water, e.g. atmospheric pressure at a temperature in the range of 20°C to 50°C, leaving methanol in the water. The methanol can be removed by distillation or by contacting the methanol containing water stream with a large volume of a C₄ stream whereby a portion of the methanol is extracted in the C₄ stream. The methanol depleted stream can recycle to contact the condensed overhead from the fractionation thereby establishing a closed circuit water wash/methanol recovery system.

Abstract: PCT No. PCT/DE91/00074 Sec. 371 Date Nov. 23, 1992 Sec. 102(e) Date Nov. 23, 1992 PCT Filed Jan. 23, 1991 PCT Pub. No. WO91/15050 PCT Pub. Date Oct. 3, 1991.A short-circuiting and brush-lifting device comprises a rotatable actuating ring having with brush-actuating rods levers cause the brushes of the motor to lift up via the rotating actuating after the slip rings have been short-circuited as a result of the axial displacement of a short-circuiting ring. To make the device wear-resistant and insensitive to contamination, the actuating ring supports three rollers, with which it abuts in the starting position on the spring-loaded short-circuiting ring. The actuating ring is guided exactly in parallel by three axial guide rods, which are disposed perpendicularly to the brush-actuating rods. The configuration of all articulated joints of these rods is adjusted so as to allow the points of maximum excursion of the deflection of the articulated joint of the axial guide rods and the brush-actuating rods are exhibited at staggered times. In this manner the brush-actuating rod runs through its point of maximum excursion first and, after that, the axial rod runs through its point of maximum excursion. The clearance between the short-circuit contacts of the short-circuiting ring and the short-circuit contacts of the slip rings is smaller in the starting position is than the axial movement of the actuating ring during the short-circuiting operation, so that the brushes do not lift up until after the short-circuiting operation has taken place.

Title: Paper machine for the manufacture of high bulk soft crepe paper.
Inventor: ERIKSON JAN ANDERS
IPC: D21F11/00
Filed: 1991-04-18
Abstract: A paper machine for the manufacture of a soft crepe paper grade, which in respect of bulk and softness is fully comparable to the one manufactured in a paper machine made for through-air drying by hot air, is in principle a conventional soft crepe paper machine, in which a conveying and imprinting fabric (25) is substituted for the pick-up felt. A pick-up device (23) operating with air flow picks up the web (15) from the forming fabric (9) and transfers it to the imprinting fabric (25) without any appreciable compaction of the web (15). The imprinting fabric (25) is maintained clean and dry by cleaning devices (41, 43, 45) and a device (47) for depleting the imprinting fabric (25) of water before it arrives at the pick-up device (23). Further, air current generating devices (35, 37, 39) are provided for removing water from the paper web (15) by passing air of ambient temperature through the web (15). These have a capacity that is sufficient for raising the dry solids content of the web to at least 25 % before the web arrives at the Yankee dryer (29). If desired, the paper machine may easily and in a short time be converted into a conventional soft crepe paper machine, essentially by substituting a pick-up felt for the imprinting fabric (25).
